I have updated 'server-filter' patch for busybox 1.22 in Xenial.

But unfortunately, build is now failing with error below:

networking/udhcp/dhcpc.c:89:1: error: expected identifier before '+' token
 + IF_FEATURE_UDHCPC_FILTER(OPTBIT_I,)

When updating patch to 1.22 I had to apply following hunk by hand:
